LONG DESCRIPTION
Our new 5th Generation MRCOOL® DIY® 55k BTU Multi-Zone Ductless Mini-Split Condenser is one of the most efficient and innovative units in the industry, and we’re excited to finally share it with you! On top of saving time and money because you won’t need an HVAC professional, this system will give you a good sense of accomplishment because you’ll have installed it yourself! The whole family will be able to enjoy the comfort of this condenser, because it can heat and cool up to 6 different spaces that equal up to 2290 sq. ft., giving you the ability to heat and cool an entire home to your exact specifications using a single MRCOOL® system. The system’s patented pre-charged Quick-Connect® line sets essentially fast-forward the installation of this system, enabling you to skip the evacuation and charging steps and simplifying the entire process. We utilize new R-454B refrigerant in these line sets, which is a much more environmentally friendly and efficient choice. Features like these assist this unit in achieving its impressive SEER2 of 22, and its HSPF2-4 of 10.6, both of which signify that this system will help you save money throughout the entire time you use it. These line sets are sold separately. Once you install this condenser, you’ll be met with a variety of features to help you control your comfort. One of these features is the Smart HVAC app, available on Apple and Android, that allows you to operate your system from the convenience of your phone. Set schedules, manage different modes, monitor energy consumption, and more all without having to leave the couch! You can also set up voice control through Amazon Alexa or Google Home, meaning you can control your comfort without moving a finger. This system ensures you’ll be enjoying ultimate convenience and superior comfort. The warranty for this unit is one of the best in the industry, and we’re proud to have your back. You can enjoy the peace of mind of a 5 year parts warranty, a 7 year compressor warranty, and, once you enroll in the MRCOOL® Care Program, a Limited Lifetime Replacement warranty.

Missing Dividers

Disappointed it was missing the adjustable dividers. Not great to hold dishwashing brushes. They slip right threw the side.

Sturdy. Built to last. It solves all the problems my old organizer had. Very satisfied.
Review for ARTLEO Kitchen Sink Caddy with Super Water Absorbent Diatomite Stone Sink Tray, Fast Drying Sink Organizer with High Dish Brush Holder Sponge Holder for Kitchen Sink, Stainless Steel This appears to be a sturdy organizer of stainless steel painted with a good amount of black protective paint. I ordered it to replace an inferior organizer of the same material (made by a different company altogether). This one solves the problems I had with my previous organizer which had begun to rust and break apart after six months of use. The narrow steel bars on the bottom shelf of this new organizer are supported by wider steel flats in the frame that will prevent them from breaking off the frame. (My old organizer bars broke because they were barely welded onto the frame and the repeated "pushing down" of my soap pump-bottle eventually broke them apart from the frame). The pads that prevent it from sliding across my counter in big waves (we live and travel on a boat) are secured around the steel legs as opposed to just being glued onto the bottom (like the pads of my previous organizer were, which fell off). There is no metal hanging over onto the sink edge to cause rust (like the metal that had caused rust with my old organizer.) The dish-brush holder can fit on the inside of the frame or it can hang on the outside of the organizer, which is nice because it makes more room if you have many tools that you like to use at the sink. And it can be compact if you don't. Be cautious not to remove the hanging part (dish-brush holder) too often because repeated wear can cause the paint to rub off and it could begin to rust. The "Water Absorbent Diatomite Stone" is new to me but it seems to be working just fine. I assume I will have to clean out the ridges of it as gunk forms there, but that would be the case with any sink organizer tray. I am very satisfied with this organizer, it is robust and it solves all the problems I had with my previous one. The price is on the higher side of similar organizers, currently priced at $23.99. All the best, Mrs. dr

Terrific Buy!
Color: Brown, Size: 13"D x 23.7"W x 32.7"H
I couldn't be happier with our new very handy piece of furniture. The tea/bar cart (I chose classic brown with the black iron) looks like a much more expensive purchase than it is. It's well-designed, well-made, and very easy to assemble, even for me: all of the holes, screws, bolts, etc., align perfectly for a level, sturdy, squared, and pleasing cart that can serve a multitude of purposes, depending on your household's needs. I just bought a second. They really are just that versatile and good-looking, and they require little space.

This is a great bar cart. The shelves hold up with a bunch of bottles on it. To be fair, we do not wheel it around. It just stays in one spot.
